Answer:
x = 1
Step-by-step explanation:
I'm going to convert this to decimal to make it easier to type
Since x = 1, there is no need to include it in the equation
1/4 - 8 = -7.75 + 12 = 4.25
-0.75 + 5 = 4.25
Answer:
By simplifying both sides of the equation, then isolating the variable.

Line C: y=17-x/3 Line D: y= 3x-1/3
Please I need help!!!!
Answers
Step-by-step explanation:
line A and D are parallel because they have the same koeficient 3=3
line C is perpendicular to line A because
k1*k2=-1
3*(-1/3)=-1
which is a true statement
Answer:
a) Line D is parallel to line A
b) Line C is perpendicular to line A
Step-by-step explanation:
Line A has a slope of 3 and y intercept of 6
Line C is perpendicular to A as perpendicular lines have negative reciprocal slopes. Slope of C is -1/3
Line D is parallel to A as parallel lines have identical slopes but different y intercepts. Slope of D is 3 and y intercept is -1/3
Line B mirrors Line A over the y axis. It's slope is the negative of A and it has an identical y intercept.

Find the value of x in the isosceles triangle shown below.
Answers
Answer:
Step-by-step explanation:
ΔABD ≅ ΔACD {A S A congreunt}
∠ADB ≅ ∠ADC {CPCT}
∠ADB + ∠ADC = 180 {linear pair}
2∠ADB = 180
∠ADB = 180/2
∠ADB = 90
∠ADB = ∠ADC = 90.
So, now we can use Pythagorean theorem to find x
x² = 8² - 2²
= 64 - 4 = 60
x = √60
Work out the value of x. And give a reason for your answer
Answers
Answer:
x = 120°
The triangle is an equilateral triangle and all the angles in an equilateral triangle equal 60°.
Straight lines have 180° angles.
180 - 60 = 120

Write an equation for a line parallel to y = − 2 x + 4 and passing through the point ( 2 , 1 )
Answers
Answer:
x=2y
Step-by-step explanation:
y=-2x+4 is perpendicular to the line which passes through (2,1). We know that we can use the formula y=mx+c to find the gradient of the line with the equation y=-2x+4, which will give you -2. The product of the gradient of two perpendicular lines is always -1. So the gradient of the line which passes through (2,1 ) is -½.
Now,to find the equation of the line,we use the formula y-y1=m(x–x1)which will give you the answer 2y=x when solved.

Factor the expression completely: x^4-81
Answers
Answer:
Step-by-step explanation:
Identity used: [tex]a^{2}-b^{2} = (a + b)(a -b)[/tex]
81 = 9*9 = 9²
a = x^2 and b =9
Then again 9 = 3*3.In this way, (x² - 9 ) can be again factored
[tex]x^{4} - 81 = (x^{2})^{2}-9^{2}\\\\=(x^{2} + 9)(x^{2} - 9)\\\\=(x^{2}+9) (x^{2} -3^{2})\\\\= (x^{2} + 9}(x+3)(x-3)[/tex]
